== Proof of concept (patch) == | |||
The main camera is created in CameraGroup::buildCamera and a pbuffer is allocated when you set osg::GraphicContext::Traits.pbuffer to true. These traits are available in buildCamera because we set width and height there. For debugging purpose, you can add a line like | |||
<syntaxhighlight lang="cpp">window->gc->getTraits()->pbuffer=true; | <syntaxhighlight lang="cpp">window->gc->getTraits()->pbuffer=true; | ||
</syntaxhighlight>at the end of this function. | </syntaxhighlight>at the end of this function.<ref>{{cite web |url=http://forum.flightgear.org/viewtopic.php?p=179978#p179978 | ||

For reference, to disable the window. It's the last thing before the return statement in WindowBuilder::makeDefaultTraits(bool stencil): | |||
<syntaxhighlight lang="cpp"> char* fg_gui = getenv("FG_GUI"); | |||
if (fg_gui != NULL && strcmp(fg_gui, "disabled") == 0) { | |||
printf ("danna_fg_gui: %s\n", fg_gui); | |||
traits->pbuffer = true; | |||
} | |||
